Specification of Letters Patent. Patented Apr. 16, 191 8.

Application filed. May 31, 1917. Serial No. 171,989

To all whom it may concern:

Be it known that I, CODY B. HUNTER, a citizen of the United States, residing at- Micanopy, in the county of Alachua and State ofiFlorida, have invented certain new and useful Improvements in Trenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art I to, which it appertains. to, make and use the same. 'i l i H This invention relates to wrenches and more particularly to wrenches of the adjustable jaw type, and has for its primary object to provide an adjustable wrench having a quick adjustment substituted for the ordinary type of screw adjustment, so as to allow the movable jaw to be quickly andconveniently adjusted to any desired position in a short space of time.

Another object is the provision of means for holding the slidable jaw in adjusted position, so that any accidental movement thereof is eliminated.

A further object is to provide a quick adjustable wrench, which will be easy and eco nomical to manufacture and durable and eflicient in its use.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed, and illustrated in the accompanying drawings, forming a part thereof, in which Figure 1 is a face view of the improved K quick adjustable wrench;

Fig. 2 is a face view of the improved wrench, showing parts thereof in section;

Fig. 3 is an edge view of the improved wrench;

Fig. 4: is a transverse sectional view taken on the line H of Fig. 2; and

Fig. 5 is a transverse detail sectional view taken on the line 5-5 of Fig. 2.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generically indicates the improved wrench, which includes the shank 2 having a lateral projection formed on one end thereof forming the stationary jaw 3. The opposite end of the shank 2 terminates in a reduced portion 5 having its end rounded and threaded to'receive the nut 6, which holds the collar 7 in position on the reduced portion 5. The

collar 7 has an inwardly extending reduced I portion 8, which rotatably and-slidably re ably. and. rotatably mountedl upon an en largedcircular portion 10 positioned eccentrically upon the 'centrallportionof the shank'2." The circular portion 10 projects owmli s direc i n. niwh cht e. ja tex and has an annular flange 11 formed upon one end thereof. An expansion coil spring 12 is positioned around the circular enlargement 1O and-bears against the flange 11 and one end of the hollow handle 9 and normally holds the ratchet teeth 13 formed upon the opposite end thereof engaged with the ratchet teeth 14 formed upon the collar 7 and prevents the hollow handle 9 from accidentally rotating.

A sliding jaw 15 is mounted upon the shank 2 and has a rearwardly extending rod 16 secured thereto. The rod 16 is slidably received in an aperture 17 formed in the circular enlarged portion 10 and projects into the hollow handle 9. The free end of the rod 16 has secured thereto a substantially fiat-follower 17 which has a notch 18 formed in one side thereof to slidably receive the shank 2. The follower 17 has a pin 19 projecting outwardly therefrom in a direction opposite to the shank2 and extends through the spiral slot 20 formed on the handle 9.

In operation of the improved quick adjustable wrench, the hollow handle 9 is pushed forwardly in the direction of the jaws and against the tension of the spring 12 until the ratchet teeth 13 thereof are out of engagement with the ratchet teeth 14 formed on the collar 7 and the same is free to rotate and then the movable jaw 15 is moved upon the shank in the direction desired and the pin 19 carried by the rod 16 secured to the jaw will ride in the slot 20 and the hollow handle 9 is turned simultaneously with the movement of the jaw 15 to allow the free movement of the pin 19 in the spiral slot 20. When it is desired to lock the jaw 15 against movement, the hollow handle 9 is released and the spring 12 will force the ratchet teeth 13 and 14; in engagement with each other, which will effectively prevent any rotation of the handle 9 and any movement of the movable jaw 15 is eliminated as the pin 19 carried by the jaw will engage the walls of the slot 20 and be prevented from moving.

In practice, I have found that th form of my invention, illustrated in the drawing and referred to in the above description, as the preferred embodiment, is the most efficient and practical; and realizing the conditions concurrent to the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in the details of construction, combination and arrangement of parts may be resorted to when required, without sacrificing any of the advantages of my invention, as set forth.

-What I claim as new is I A wrench comprising a shank, a jaw rigidly secured on the shank, a jaw slidably mounted on the shank, a handle rotatably and slidably mounted upon the shank, said handle having a spiral slot, a rearwardly extending arm carried by said movable jaw and extending into the hollow handle, a pin carried by and projecting outwardly from said arm into said slot, said hollow handle having a clutch face adapted to engage a cooperating clutch face formed on said shank,

and spring means normally holding the clutch face formed on said shank in engagement with the clutch face on said hollow handle, to prevent the accidental rotation thereof. 7

In testimony whereof I aflix my signature in presence of two witnesses.
